Find the missing angle according to the Triangle Sum Theorem.

x = 60°

Step-by-step explanation:

Triangle Sum Theorem: The sum of interior angles always equals 180°.

We are already given two angles, 30° and 90°. Add these together and subtract it from 180° to get your answer.

x=60

Step-by-step explanation:

Because a triangleś angles need to be summed to 180 degreeś.

90+30+x=180

180-90=90

90-30=60

x=60

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
